Pelicans and flying rays

The pelican’s a funny bird, its feathers could be cleaner
Though if its beak were half the size it would be somewhat leaner.
And when below it sees a ray a fishin’ in the water
It fights the urge to dive on in and join in with the slaughter.
The ray’s a jealous type you see, despite its calm demeanour,
The only way to calm it down is cans of Orangina.
